<p>PURPOSE:To easily attach and detach electric precipitation elements by a method wherein a plurality of the electric precipitation elements are received in a frame body supported so as to be capable of being drawn out to the lateral part of a casing by a roller in a mutually independent state in a freely detachable manner. CONSTITUTION:A frame body 6 has a rectangular shape whose surface exactly opposed to an air passage B is opened and electric precipitation elements 9 are provided in the frame body 6 so as to be detachable from the open surface thereof. The frame body 6 is supported in a casing 1a in a freely slidable manner by a plurality of the rollers 11 arranged to the bottom part of the casing 1a at a predetermined interval and the upper rollers 61 coming into contact with the casing 1a in rotatable manner are provided to the inner deep part of the upper surface of the frame body 6. By this constitution, the electric precipitation elements 9 can be taken out to a room one by one at a time through an opening part 8a by detaching the electric precipitation element 9 from the frame body 6 while the frame body 6 is successively drawn out to the lateral part of the casing 1a in such a state that the opening part 8a of a ceiling 8 is opened and the side plate 1c of the casing 1a of a dust collection unit is detached.</p> |
